Action-Reaction Law

The action-reaction law, also known as Newton's third law of motion, states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts a force of equal magnitude in the opposite direction on the first object.

Explanation

When you push against a wall, the wall pushes back on you with an equal force in the opposite direction. This is an example of Newton's third law in action. The force you exert on the wall is the action, and the force the wall exerts back on you is the reaction.
